Operators of time & temperature lines often see a spike in calls twice a year – when the time changes. Lots of people call to confirm that they have set the right time on the clocks in their homes, and they want to confirm that their cell phones have changed to the correct time!
An article about the time change in a Scottsboro, Alabama newspaper mentions the option of calling the local Time & Temp line. The operator of the service in Scottsboro (population about 15,000) gets about 35,000 calls per month.
By the way – WeatherNow Time & Temp systems from RTI Media automatically change to the correct time twice each year. Read about Scottsboro here.
